JOHN C. IIOLLINGS, OF BOSTON, MASSACHUSETTS.

ELECTRIC-LIGHT FIXTURE.

SPECIFICATION formingpart of Letters Patent No. 410,689, dated September10, 1889.

Application filed March 26, 1889x To all whom it may concern.-

Be it known that I, JOHN C. HOLLINGS, of Boston, county of Suffolk,State of Massachusetts, have invented an Improvement in Fixtures forLights, of which the following description, in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

As fixturessuch as chandeliers,brackets, &c.are now made, much troubleand ineonvenience are experienced in applying to the same'electric wiresemployed either to convey the electric current to an incandescent lightbulb or merely to convey electricity to a lighting contrivance. Toobviate this difficulty and avoid making holes in the outer covering orjacket of the fixture and to avoid taking the fixture down, I haveseparated the jacket or covering of the fixture, so that one part may bemoved longitudinally on or with relation to the other and with relationto the main standard or a fixed part of the fixture, the movement of thecovering, as described, affording ready access for the wire into thespace between the covering and the standard or rigid part of thefixture. To yet further aid in this operation of wiring the fixture, asit is called, I provide a locking device whereby two parts of thecovering may be locked together when shortened by telescopic movement,so as to be moved together by the operator.

My invention consists, essentially, in the combination,with the standardor body of a fixture, of a longitudinally-movable or telescopiccovering; also the combination,with the standard or body of a fixture,of atelescopic covering and a locking device, substantially as will bedescribed.

Figure 1 in elevation represents a fixture supposed to be extended froma piece of gas or other pipe protruded through the ceiling, the mainstandard of the fixture being inclosed by one form of a jacket orcovering embodying my invention, and Fig. 2 is a partial verticalsection of the fixture shown in Fig. 1, but with the covering shortenedby telescoping one part into the other, the covering being supposed tobe held up by the hand of the operator or otherwise so as to Serial No.304,846. (No model.)

leave an open space at both ends of the cover- 111".

lteferring to the drawings, a is supposed to represent the main body orstandard of a fixture, and a its arms. It will of course be understoodin practice that the standard and arms will be covered with a suitablejacket or covering to constitute the exterior orornamental part of thefixture, such jacket or covering being composed chiefly of tubes ofbrass or other material and of ornamental portions in great variety.

The jacket or covering herein shown is supposed to consist, essentially,of a tube 1) and a tube a, which are telescopically arranged one withrelation to the other outside of and to surround the standard a. Onepart of the jacket or covering, as c, is shown as provided with acollar, as 0', through which is extended a locking device, as (1, shownas a set-screw, the inner end of the set-screw acting against theexterior of the part b,thus enabling the covering when movedtelescopically one part with relation to the other to be fixed together,so that the operator by engaging any part of the covering may lift thesame to obtain ready access to the wire below the lower part c of thecovering. The collar 0 is shown as connected to the tube 0 by aset-screw 3.

It will be obvious that the external appearance of the covering may bevaried Without departure from my invention so long as the covering istelescopically arranged; and, further, it will be obvious that myinvention may be applied to any form of fixture wherein it is desired toconceal a wire between the covering and the main body or standard of thefixture composed of'a cheaper material than its covering.

I claim 1. A fixture a, of ordinary or approved construction, asdescribed, combined with tubes 1) c, of greater diameter than thefixture and adapted to be telescoped one within the other 5 to uncoverthe space between the said fixture and the said tubes, substantially asand for the purpose described.

2. A fixture a, of ordinary or approved construction, as described,combined with the surrounding tubes b c, of greater diameter Intestimonywhereoflhavesigned my name 10 than the fixture to leave a spacebetween to this specification in thepresence of two subthem and thefixture for the reception of elecscribing witnesses.

- trio conductors, the said tubes being adapted 5 to be telescoped onewithin the other to un- JOHN C. HOLLINGS.

cover the space between the fixture and the tubes, and a locking devicefor retaining the Witnesses: tubes in adjusted position, substantiallyas GEO. W. GREGORY, and for the purpose set forth. FRED. S. GREENLEAF.
